Looking to change the order in which templates appear at Oxygen > Templates in the backend of your Oxygen-powered WordPress site?
Post Types Order plugin can be used to reorder entries of any post type and it works with Oxygen’s Templates as well.
But there’s a small problem: “Re-Order” admin menu item will not get added under “Oxygen” admin menu item unlike how it happens with other “regular” post types.
So after you install and activate the plugin, go to Oxygen > Templates page and tack this on at the end:
&page=order-post-types-ct_template
Example of the full URL: https://oxygen.test/wp-admin/edit.php?post_type=ct_template&page=order-post-types-ct_template
You will be presented with all the templates and to rearrange the order, just drag and drop and click the Update button.
